Siege and Surrender
After the Meccans' withdrawal, Muhammad then led his forces against the Banu Qurayza neighborhood. According to the Muslim tradition, he had been asked to do so by the angel Gabriel. The Banu Qurayza retreated into their stronghold and endured the siege for 25 days. As their morale waned, Ka'b ibn Asad suggested three alternative ways out of their predicament: embrace Islam; kill their own children and women, then rush out for a charge to either win or die; or make a surprise attack on the Sabbath. The Banu Qurayza accepted none of these alternatives. Instead they asked to confer with Abu Lubaba, one of their allies from the Aws. According to Ibn Ishaq, Abu Lubaba felt pity for the women and children of the tribe who were crying and when asked whether the Qurayza should surrender to Muhammad, advised them to do so. However he also "made a sign with his hand toward his throat, indicating that at the hands of the Prophet would be slaughter". The next morning, the Banu Qurayza surrendered and the Muslims seized their stronghold and their stores. The men - numbering between 400 and 900 - were bound and placed under the custody of Muhammad ibn Maslamah, who had killed Ka'b ibn al-Ashraf, while the women and children - numbering about 1,000 - were placed under Abdullah ibn Sallam, a former rabbi who had converted to Islam.
However Ibn Sa'd gives the following account:
"The Apostle of Allah, may Allah bless him, authorised Sa'd ibn Mu'adh to give a decision about them. He passed an order: He who is subjected to razors (i.e. the male) should be killed, women and children should be enslaved and property should be distributed. Thereupon the Apostle of Allah, may Allah bless him, said: You have decided in confirmation to the judgement of Allah, above the seven heavens. The Apostle of Allah, may Allah bless him, returned on Thursday 7 Dhu al- Hijjah. Then he commanded them to be brought into al-Madinah where ditches were dug in the market. The Apostle of Allah, may Allah bless him, sat with his Companions and they were brought in small groups. Their heads were struck off."
